Starlink v1.0 L16 discussionThe probability of a Starlink launch in December is low, but with the NROL-108 delay anything can happen.

By my count every available booster must have already been committed. And in fact we are one short for the payloads already on the schedule.
B1049.7 will launch either Starlink v1.0 L15 as a flight leader or SXM-7 due to contractual commitments.

Why so convinced SpaceX would ever use a flight leader for commercial payloads?Seems very far fetched and extremely unlikely to me. And we have several SpaceX missions that are available for such higher risk flights. Transporter-1 and Starlink-L17.
The risk between a .6 launch and a .7 launch is nominal, especially when 1049.7 is going up first.

I was reading this thread and thinking 'wow, we're getting really close to 10'
Transporter-1 is also external payloads. They're running low on boosters. The lowest available are .4's unless you wait for the one from Sentinel 6 to be refurbished. Maybe a customer would be willing to give it a shot for schedule certainty or a discount?

Maybe a customer would be willing to give it a shot for schedule certainty or a discount?I know we've heard that booster production has been scaled back significantly, but with 1061 and 1062 being put on ice for 4+ months, it wouldn't surprise me if there is an extra new core or two laying around Hawthore ready to ship if the schedule required it. Consider that 1057 was flown (and sadly lost) nearly a year and a half ago!
B1064-B1066 are part of the next Falcon Heavy launch. There is another FH launch soon after that which will require another 3 new cores. That would pretty much use up production capacity from July 2020 through March 2021.

That would pretty much use up production capacity from July 2020 through March 2021.Wow, that's right...they'll have quite a lot of FH boosters piling up that they can't readily use for FH flights because the Space Force is (for now) still insisting on new ones. Given the evident crunch for F9 boosters at the Cape, I wonder if we'll finally see them converting some of the side cores to single-stick F9s. If we don't see them doing that now, of all times, that would suggest they have a really good reason not to, which we aren't privy to.I keep waiting for them to convert 1052 and 1053 to F9s, but for them to have sat on them this long suggests it's not as easy as has been assumed. It's been over a year since they've last flown, and it wouldn't make sense to save them for FH usage as they've known the next two FH missions would require all-new boosters. (Unless maybe they were hoping to cajole the Space Force into accepting a reflight on USSF-44, though that obviously didn't pan out as we've seen 1064 at McGregor.) Perhaps there's something about the first B5 FH that was "odd" and makes the conversion less "plug and play" than they previously said it was designed to be. Or maybe they scrapped that idea for whatever reason and didn't end up designing them for easy conversion after all. Who knows...

This requirement suggests the next boosters through McGregor, B1065 and B1066, will also be Falcon Heavy stages for the USSF-44 mission.
I think there hasn't been any official confirmation, however the timeline of this booster being in McGregor suggests it's 1064 and it was confirmed that this is a Falcon Heavy side booster.https://twitter.com/nasaspaceflight/status/1309548574053675008https://twitter.com/SciGuySpace/status/1309540792688574465From the NSF article by Thomas Burghardt: https://www.nasaspaceflight.com/2020/09/spacex-manifest-falcon-heavy-arrives-mcgregor/QuoteThis requirement suggests the next boosters through McGregor, B1065 and B1066, will also be Falcon Heavy stages for the USSF-44 mission.Next Spaceflight also claims this is the case and Michael seems to have a good source for booster assignments.
Can a side booster from a Falcon Heavy be used for a standard Falcon 9 launch?
